Thumbs up 2004 Duramax 6.6 Liter Diesel Engine Assembly Torque Specifications

Can anyone help me with this engine main and Rod bearings tightening torque specifications, as well as the cylinder heads torque specifications? I am replacing new piston rings and Rod bearings but I do not have this torquing information.

thanks in advance

Someone may want to spot check this list, copied from my LB7 manual (2002 vintage - things change). Should be correct or close for 2004, but no guarantees.

So you are doing this work without a manual??
